ASB will open a new Northland regional centre in central Whangarei in late 2017.
The new, purpose-built 700 square metre facility will be built at 5 Rathbone St, the former site of Stirling Sports, almost directly across the road from the bank's existing branch.
ASB said "the same friendly, local branch team" will be housed on the ground floor relocated from the existing branch across the street at 8 Rathbone St.
ASB executive general manager corporate, commercial and rural Steve Jurkovich said ASB's proud history in Northland's communities stretches back more than 50 years, and extends to its strong partnership with Sport Northland today.
"ASB has strong history in Northland and it's exciting to be able to build on our relationships within the community through a brand-new base in the heart of the Northland economy," he said.
